' ca'se which as shown is rectangular in form and bolted to the under surface and at the rear end of the water case or jacket lfi as seen in Figs. 1 and 2. i y

In the forward end of the gas and vapor mixing case is an opening 20 for the reception of gas from the gas carburetor (not shown) the pins 21 on the outer ends of 'the case and on each side of the opening being means of attachment for the carburetor. In the top of the gas and 'vapor mixing chamber 19 beneath the cylinder 12 is an opening or inlet 22,,and in the bottom of-the case or water jacket 14 directly above the opening 22 is an opening 23 in which is a valve seat and seated in said valve seatis a valve 25. With the valve 25 is connected a valve stem 26 the lower end of which stem extends downwardlythrough the bottom of the case 19, and also through a boss 27 on the under side of said b'ottom of said case and to a considerable distance below the outer surface of said boss. The lower end of the valve stem 26 is screw'threaded and provided with a nut 28. Extending around the valve stem 26 is a spiral spring 29, one end of which spring bears upon the nut 28 and the other end upon the outer surface of the boss 27.

Within the case or jacket 14 and extending around the opening 23 is a neck 30 connected with the bottom of said case, the upper end of the neck being connected with the'outer surface of the cylinder 12. In the; cylinder '12 is an opening 31. leading within the neck 30. The construction of the parts of the gas engine as above described are common in all gas' or gasolene engines and also the gas igniting devices re- '85 quire no special mention as these devices are well known and any of which may be employed.

7 With the forward end of the engine supporting or base frame are connected the lower ends of the bars 32 and with the upper endsof said bars is connected a water supply tank 33 which is designed to hold the water requisite forlthe daily use in the engine and compared with the ordinary water tanks in use is smaller in water capacity. I v j j The tank 33 as shown is cylindrical in form and the bars 32 are secured to the side and lower portion of the casing adjacent to the ends 34 of the .tank. In the upper portion of the .side of tank 33 near one end is an opening for the introduction of water to the tank extending around which opening is a receptacle or cup 36, upon the lower end of which cup is a flange 37 which extends outwardly and is bolted to the side of the casing of the tank. Within the receptacle 36 is an ordinary valve and valve stem 43.

With one end 34 of the water tank 33 is connected a water gage 49 this gage having connections with the upper and lower parts of the said tank.

Within the portion of the side of thewater tank 33 short distance below a line projected from the under.

toward the engine and intermediate the top and bottom of the tank and below the ordinary water line or surface of the wateris connected one end of an ingoing water conducting pipe 50, the other end of which pipe extends horizontally a short distance to a position above the water jacket 14 'and is then beat at right angles and its lower end extended downwardly through the top of the case or water jacket and a slight distance within the space between the cylinder 12 and the said water jacket as seen in Fig. 2.

A'separate outgoing water supply pipe 51 is connected at one end with the same side of tank 33' with which pipe 50 is connected and-with the lower portion of.the side and bottom of said tank. The other end of pipe 51 extends downwardly to a position a I surface of the water jacket 14, and is bent at-right angles and extended to a position directly beneath the water jacket and provided with an elbow 52, with slight distance within the space betweers-the water jacket and cylinder 12.

With the. top portion of the side of the tank 33- is connected a steam supply pipe which'is in separate parts 54, 54 'one part 54 being connected at one end with the said portion of the tank, the other end extends within an opening 55 in the side of a condensing case or trap 56. This case resembles an inverted flask and is flat upon each side, the sides and ends of th'ecase terminating in a: neck 57. This neck extends downwardly "and within the neck is a screw threaded passage 58.' Within the case '56 is a partition or diaphragm 59 which is'connected with the ends of the case at a point equidistant from the sides and extends from the inner surface of the upper end of the case downwardly to a position ashort distance above the neck 57 so as to form a by pass for the steam. In the screw threaded opening 58 in the neck 57 is inserted-one. end of a drip pipe 60 the other end extendingldownwardly the desired distance.

In the opposite side of the case 56 to that having the opening 55 is a screw threaded opening 61 in which is inserted one end of the other portion 54 of the steam pipe, the other end of which pipe extends to a point a short distance in" rear of a vertical line extending through thexear end of the cylinder 12 of the engine and is bent at right angles and extended downwardly to a position opposite the, gas and vapor mixing case 19,, upon which end-is an elbow 62 with which elbow is connected one end of a short length of pipe-63. Upon the other end of pipe 63 is a three way pipe joint. 64 and with this joint is connected one end of a short lengthof pipe'65 the other end of which pipe extendsthrough an opening 6 5 see Fig.' 3. in the other side of the gas and vapor mixing case 19 at a point opposite the valve stem 26 the pipe 65 terminating near said valve stem. With the upwardly extended opening ofv the three way pipe joint 64 is connected the lower end of a short length of pipe 66,

the upper end of said pipe ex tending to a'position opposite the lower portion of the rear end of the water 69. With the inner end of the valve casing 67 is c031 end of which pipe extends through the end of the water jacket into the space between the inner surface adjacent to the valve stem and directly beneath the inner end of the pipe 65 and into which the water falls in the initial operation of the engine from condensation of the steam from said pipe as well as from the walls of the gas and vapor mixing case.

In operation the water is supplied to the tank 33 through the receptacle 36 in sufficient quantity to fill the ank and permit of an overflow into the pipes 50'and 51 to the space within the water jacket surrounding the cylinder 12. This space beingfilled with water and also thetank to the level above pipe 50 the valve 43 is closed. The valve stem 68 is then operated by the hand wheel 69 to admit a slight quantity of water from the water jacket into the gas and vapor mixing case 19 which falls or drips into the depression 71 in the bottom of the said case an excess of water passing from the case through the orifice 71 The carbureted gas is then supplied to the gas and vapor mixing case 19 through the opening 20 from the carbureter or other source of gas supply. The gas under the suctionofithe engine raises the inlet valve 23 and at the same time this suction of the engine takes up the water in the depression 71, in the case 19, and the water and gas is drawn simultaneously within the cylinder 12; The gas is then ignited in the usual manner and the initial movements of the piston accelerated by turning the drive wheel 17 and under the repeated explosions of the gas the water admitted with the gas prevents pre-ignition and the force of the explosions are communicated to the drive and balance wheels. As soon as the engine has been operated a short time the valve 68 is closed. The heat caused by the ignition of the gas will obviously heat the cylinderand this heat will' be absorbed by the water-in the water jacket surrounding the cylinder, the temperature of the water being gradually raised and circulation of the water formed in the water tank 33, the high degree of heat of the cylinder finally producing steam. As soon as steam is generated in the tank it passes into the steam pipe 54 through the steam condensing trap 56 air und the ,lower edge or by pass of the diaphragm 59, thence upwardly and into the other portion 54 of the steam pipe, the condensed water being discharged from tln- -pipe 60. The steanrwhich now passes through pipi- 65 into the gas and vapor mixing chamber is llllxl ll with the carbureted gas in the mixing case 19 and fill-$124 into the cylinder 12 vaporized with the gas and affords an element upon which the piston-acts to Compress and the piston is given an impetus with the expansion of the steam when the piston has compressed the mixture of the gas and steam during the time the ignition of seas-2:

thus abrogating the necessity oi a large water circulation to draw off the heat hour the cylinder and affording with the steam produced a water tank supply of minimum proportions. The tank 33 when supplied with water enables the engine to be operated a longer time without renewing the supply, the height of which water can be observed in the water gage 49. in .a. portable gasolene engine this advantage of a small tank of water affording all of the water necessary ior cooling is obvious and the engine may be employed in various places and for a long period oi time with one supply of Water to the tank.

I do not limit myself to the source of supply of steam from the tank, as other sources may be had. the means of steam supply shown being preferred and the location of the water tank may be in any desired place above the engine so as to obviate the necessity oi a pump for water circulation.

-Such modifications oi the invention may be employed as are Within the scope of the invention.
